Very good location. Many restaurants within walking distance. You can take a taxi to the MRT Tao Poon. Trip to the station is about 10 to 15 min.
if you are looking to extend your visa. Go to the Tao Poon station blue line. Get off at Bang Sue Station. Take the Redline from Bang Sue. Get off at Lak Si . The immigration office is called IT square immigration office on the 3rd floor in bangkok.
As for downtown Bangkok. You can take the blue line all the way to Sukhumvit station
My stay at this airbnb was great!!!
